Build a set of shooting sticks so you can shoot standing. If you shoot from a bench, sit up straight.

My first attempt with regulating my 45.70 was with 350 grain bullets before I got the regulating instructions. The left barrel was shooting 3" higher than the right and the right barrel was crossing the left about 4" (all at 50 yards). I made a half of a turn adjustment on the jackscrew and loaded up some 300 grain bullets using H322 powder to shoot tomorrow.
